An Exit Strategy for School Safety
Apr 1, 2011 12:00 PM, By Mike Kennedy
To ensure the security of an education facility, administrators need to select the appropriate kinds of doors.
A school should have the fewest possible number of exterior doors to deter unwanted intruders from gaining undetected entry.
When a new school facility opens, most of the staff and students are eager to get inside quickly and check out the new surroundings and all the cool stuff that will make their days of teaching and learning more comfortable and enjoyable.
In their excitement, they are unlikely to pay much attention to what every one of them has to pass through to get to their destination: the doors into the school. And, really, why should they? When technology-laden classrooms and labs are waiting with their new-building smell, who has time to think about doors?
In a well-designed school, administrators and designers have given a lot of thought to doors—the ones that let people in and out of the building, as well as the ones that separate spaces inside the facility.
In deciding what kind of doors will be installed, schools and universities have to consider who will be coming in and out of them; how much control they want over those comings and goings; what level of monitoring is necessary and desirable for each entryway; what amount of technology can be included to assist that monitoring; how much wear and tear the doors are expected to endure from a constant flow of students and staff; how much protection they are expected to provide from fires, hurricanes, tornados or external contaminants; and when and how they can be locked or unlocked. Oh, and they also should look nice.
Seeking security
The need for greater school safety and security at education institutions, along with the ever-widening selection of technological products to bolster that security, have added several layers of decisionmaking to selecting doors for a school campus.
Federal statistics state that from 1999-2000 to 2007-08 school years, the percentage of public schools that had controlled access to buildings during school hours increased from 75 percent to 90 percent; the percentage of schools that used controlled access to school grounds during school hours climbed from 34 percent to 43 percent; and the use of one or more security cameras to monitor school facilities rose from 19 percent of schools to 55 percent.
The National Clearinghouse for Educational Facilities (NCEF) has compiled numerous tips that can help facilities managers choose the right kind of doors:
•Exterior doors. A school should have the fewest possible number of exterior doors to deter unwanted intruders from gaining undetected entry. These doors should have as little exposed hardware as possible and be protected with pick plates (to prevent prying or other vandalism that could lead to unauthorized entry). They should be made of durable material—steel, aluminum alloy, or solid-core hardwood. For doors where monitoring by staff is not feasible and students are able to open doors and admit unauthorized visitors, schools should bolster security with door alarms, delayed-opening devices, sensors or video surveillance.
•Entry areas. Schools should consider a remote-entry system controlled from the school officer or a reception area. The doors should be situated so that visitors are guided to report to the school office before going elsewhere in the building. School safety is key.
•Access control. Because keys can be easily lost or stolen, and replacement can take a long time and be labor-intensive, education facilities should consider controlling access electronically through swipe or proximity cards, keypads, biometrics, or some combination of them.
•Interior doors. The hardware for these doors should be designed to prevent vandals or criminals from locking them and slowing or stopping security officers from pursuing them. (In the 2007 Virginia Tech shootings, the gunman used chains to lock himself and his victims inside the classroom building where most of the shootings occurred.) In spaces where students can lock themselves in, school officials should have a way (e.g., a master key or a proximity card) to unlock the door. When interior doors are opened, they should not project more than 7 inches into a corridor. When openings are not wide enough, students are more likely to trip and injure themselves, and the congestion created by narrowing the passageway can lead to heightened tensions, shoving and fighting among students.
•Classroom doors. The hardware for classroom doors should enable staff members to quickly lock down classrooms from the inside without having to step into the hallway. The NCEF recommends dual-cylinder ANSI F88 locksets; they enable doors to be locked from either side to prevent entry from the hallway, but in accordance with fire codes, they can’t be locked to prevent students or others from exiting a classroom in an emergency.
